MACHINE non gamma FUR-NAIBPED some:

To allwiwmit may concern: r

' Be it known that I, GEORGE Gnovnn,'a citizen of the United States, residing: at: the city of South Norwalk, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Scalding Fur- Napped Bodies; and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for scalding fur napped bodies. p

In the artof making fur nappedhats, a substantial felt body is used as a base and on this loose fur particles are distributed which are firmly united to the body by the application of hot water and intermittent kneading processes.

Heretofore these bodies, with the fur stuclc thereon by an initial application of hot water and hand pressure, are preferably rolled into bundles-encased in any suitable thin cloth, and are then subjected tothe action of felting or sizingrolls,which latter are provided with exterior lags whereby the proper kneading processis'applied to the hats, and these hat bundles are frequently dipped in the scalding water" and subjectedto this felting process quite a number of times.

While the above process is commonly ap plied and is preferable with respect to the ordinary fur hats which are for1ned completely by this felting or sizing process, nevertheless in the instance of fur napped hats this process is so slow'and requires so much attention that it is quite expensive, and it is the object of the presentinvention to produce a structure whereby fur napped hats may be treated most expeditiously and also greatly improved in the uniformity of the napped surface.

Furthermore, this invention contemplates an entirely new process in the scalding and felting of fur napped bodies, and consists broadly in tumbling these bodies within perforated closed cylinders that have lags extending from the interior walls thereof, the cylinders having no axial movement,

but being carried orbitally so as to be inter-- mittently submerged within and emerged from the scalding water in the tub, the water readily entering the perforations in in the cylinders.

the cylinders when the latter are submerged,

the cylinders are; constantly beingscalded and tumbled against the lags, and this "is repeated until the felting process is completed. 'j- I In order that the statements made above may more readily be understood and ap- -preciated,adescription of the invention will now be given'm more or less detail, with especial reference to the drawings which form apart of this application and which show one form in WlllCll' the invention is exemplified;

- Referring to these drawings' I Figi 1re 1 is a side elevationof amachine which-is particularly adapted "for carrying outthisinvention; v I i Figure 2 is a central longitudinal section of the machine;

Figure Bis a front elevation; and Figure 4. a detail sectional elevationof one Similai nuinerals of reference denote like 1 is the frame of the machine and 2 any suitable scalding tub secured thereto. 3 is a shaft journaled'on the frame and having keyed thereon the cheek pieces 4:.

5 are hollow cylinders preferably made of wood which are secured at their ends to the cheek pieces 4: and surround the shaft 3, so that it will be clear that, as the shaft revolves, these cylinders will be carried around orbitally. or, in a circular path around said shaft.

Eachcylinder has a 'door 6 which is secured. in closed condition in any suitable manner, as, for instance, by a hasp 7 on the door, a perforated stud 8 projecting from the cylinder, and a pin 9, the latter being inserted through the perforated stud after locking engagement with the hasp.

- Each cylinder, including its door, is perparts in theseveral figures ofth'e drawing.

forated at numerous locations, as shown at extend lengthwise of the cylinders, any style of lags disposed in any suitable manner may be employed. v I

"The! tub is supplied with scalding water in the manner usual in hat felting machines, and, as the shaft revolves, the cylinders will be submerged within and emerged from the water, the latter entering and draining through the perforations 10.

The felt bodies coated with fur by the usual initial sticking process, are either bundled within a suitable cloth and cast into the cylinders, or such bodies may be placed in the cylinders with no cloth covering whatever, and,

during the revolution of the shaft, said bodies will be tumbled around; the cylinders and against the lags, and alternately saturated with h-ot water and drained thereof, and this process continues until the felting is completed. v

Napped hats treated by this process are superior in every respect. The fur is more closely and uniformly felted, and, moreover, the machine 1s a great saver of labor.-

Having thus described this invention what is claimed is frame, and a series of hollow perforated cylinders having internally projecting lags and carried by said shaft in radial disposition thereto, said cylinders being each provided with perforated doors likewise having lags projecting from their interior surfaces:

3. In a machine of the character described, the combination of a frame, a scalding tub supported thereby, a shaft journaled on said frame, and a series of hollow perforat-ed cylinders carried by said shaft and arranged in radial circular disposition thereto, each cylinder having internally projecting lags and a perforated door likewise having internally projecting lags, the nappedfelt bodies being placed within the cylinders and the doors closed and thereafter the cylinders being dipped during their rotation. within the scalding water in the tub.

4. In a machine. of the character described, a frame, a scalding tub support-ed thereby, a shaft journaled in said frame, and a plurality of perforated hollow cylinders orbitally surrounding said shaft and rigid therewith and having no independent axial movement, the cylinders having internally projecting lags and being carried by the rotation of the shaft so as to submerge within and emerge from the scalding tub, while each cylinder has a door.

5. The herein'described process of scalding nap-ped fur bodies, which consists in turnbling them within hollow perforated orbitally revolved cylinders having no axial revolution and provided with internal lags, and intermittently and continuously subjecting said bodies to scalding and draining.

.In testimony whereof I afiix my signature hereto.
